Moreover it is required in stewards that one be found faithful. 1 Corinthians 4:2
The stories of Navy SEAL training are legendary—perhaps the most demanding of any military branch. Why do the SEALs (along with the Army Rangers, Deltas, Special Forces, and others) endure such rigorous training? So that trainees will count the cost before committing. So they will be faithful in the heat of battle. It’s why the Marine Corps motto is Semper Fidelis—“Always Faithful.”
Faithfulness. It’s at the heart of every mission statement—military, business, family, or church. The apostle Paul said only one thing is required of stewards: to be faithful. Paul was a steward of Christ’s commission to take the Gospel to the Gentiles (Acts 26:17-18). But of what is every Christian a steward? The Great Commission, to begin with (Matthew 28:19-20). But also, we are stewards of the love and grace of God that has been poured into us by the Spirit (Romans 5:5). Such love and grace was given at great cost—the life of Jesus Himself.
Jesus warned the crowds that followed Him to count the cost before committing (Luke 14:25-33). Once committed, faithfulness is all that matters. Authentic Christians are true stewards; true stewards are faithful forever.
Stewardship is what a man does after he says, “I believe.” W. H. Greaves
